Description

Raise the stance of your classic GM 4x4 with the Tuff Country 16611KN 6" Lift Kit. Designed for 1969–1972 Chevy and GMC 4WD trucks, Blazers, and Suburbans, this kit combines rugged engineering with a smoother ride thanks to EZ-Ride leaf springs, a steering arm, 52" rear springs, and SX8000 shocks.

  • Lift Height: 6" front and 6" rear, providing sturdy ground clearance and room for larger tires (up to 35" x 12.5").
  • EZ-Ride Leaf Springs: engineered for improved ride quality with Teflon pads to reduce noise and squeaks; polyurethane bushings included for durability and responsive handling.
  • Shocks Included: SX8000 shocks are included to deliver balanced damping that complements the lift and improves on- and off-road control.
  • Rear Springs: 52" long rear leaf springs to support load capacity and maintain a stable ride height.
  • Steering Arm: built-in steering arm preserves steering geometry after the lift, helping maintain precise steering feel on rough terrain.
  • Fitment & Compatibility: designed for 1969–1972 Chevy/GMC 4WD models (Blazer, Suburban K1500/K2500, and trucks); not compatible with diesel engines; fits 1/2-ton and 3/4-ton variants; driveshafts must be extended and factory shocks replaced with extended shocks for proper installation.
  • Warranty: limited lifetime warranty on the leaf springs; the entire kit is backed by a limited lifetime warranty for long-lasting confidence.
  • Made in the USA: built with Tuff Country’s engineering standards to deliver reliable, durable suspension components.

This kit is designed to deliver a practical, capable upgrade: enhanced ground clearance for rugged trails, the ability to run larger tires, and maintained steering control across varied terrain. EZ-Ride springs work with the included components to reduce noise and improve ride quality, while the steering arm and SX8000 shocks help keep your vehicle confident on and off the pavement. With a lifetime warranty backing the leaf springs and the kit, you’re investing in a proven, long-term solution for your classic GM 4x4. Note the installation requirements: extended shocks are necessary, driveshafts must be lengthened, and the setup is best suited for small-block engines to optimize performance.
